Definitions

  • Lathces shape a rotating workpiece with a tool, for example, a nonrotating tool bit, boring bit, or similar cutting tool or cutter, which is exclusively moved in cooperating manner with respect to the workpiece by an advancing device i.e. the tool slide which can have a cross feed and can carry a tool post.
  • a tool for example, a nonrotating tool bit, boring bit, or similar cutting tool or cutter
  • an advancing device i.e. the tool slide which can have a cross feed and can carry a tool post.
  • Many machining operations require an additional tool, such as a milling head or a drilling tool, for example.
  • a groove intended for a key or the like therein can be produced by milling of the corresponding groove opening. This machining operation can be carried out after removing the workpiece from the lathe and by securing or chucking it in a milling machine.
  • the toolhead has two separate devices, one each respectively for a fixed tool and for a rotating tool, with each movement of the toolhead - i.e. during the tool exchange, as well as during longitudinal or planar movements with respect to one production position - care must be taken that collisions of parts of the machine or a part of the machine with the workpiece are avoided.
  • the one tool retainer device is equipped with a cutter, or a tool holder and cutter, and the other tool retainer device is equipped with a drill rod of wide working range, it is clear that the latitude of the toolhead is considerably restricted. When one tool is removed, and the respective retainer is left empty, such retainer is prone to accumulate dirt, for example, turnings or similar chips, and the machine is liable to be disrupted in its functioning. Thus covers are necessary for the exposed parts.
  • a toolhead which has a single tool post or tool retainer for a tool carrier or tool clamp for fixed or rotating tools, or for directly mounting fixed or rotating tools, and the tool post or tool retainer is provided with a drive gear wheel or drive components for coupling the rotating tools.
  • a toolhead which can be mounted on the cross slide and which is formed with a seat provided with tool-drive gearing, the seat selectively receiving either a nonrotatable-tool carrier or a rotatable-tool carrier, the latter having tool-rotating gearing meshing with the tool-drive gearing of the head.
  • Any conventional means can be used to detachably retain the carriers in the seat.
  • the toolhead is adapted to be rotated about an axis which is at an angle of 45° with respect to the main axis (z-axis) of the machine tool and the transverse axis or plane axis (x-axis), and intersects the line of intersection of the tool retainer or holder planes which extend parallel with respect to the longitudinal and transverse planes.
  • the toolhead can accordingly be used with magazines to the right or left of the cross or transverse slide. Because lengthy rotating tools, for example, drilling tools, can be laid down in a direction parallel with respect to the machine axis, no special limitations arise for the tool latitude during working in the transverse direction (x-axis).
  • journal arrangement for the rotating tool is directly mounted in the tool retainer or seat of the toolhead.
  • journal arrangement for the driven tools is arranged in the tool carrier.
  • FIG. 1 is a schematic plan view of a toolhead with a tool carrier mounted thereon and a rotating tool, whose axis of rotation extends in the direction of the z-axis of the machine tool about which the workpiece is rotated;
  • FIG. 2 is a view similar to FIG. 1 with the toolhead having been rotated through an angle of 180° so that the tool axis now extends in the direction of the x-axis;
  • FIG. 3 is a schamatic view of a toolhead with a tool carrier and a cutter for lathe operations adapted to feed and extending in the direction of the x-axis;
  • FIG. 4 is a view similar to the arrangement according to FIG. 3 after rotation through an angle of 180° so that the tool extends in the direction of the z-axis;
  • FIG. 5 is a schematic view of a toolhead for rotating tools with installed journal arrangement
  • FIG. 6 is a view similar to FIG. 5 with a tool holder and a lathe cutter substituted for the rotatable tool of FIG. 5.
  • a lathe is a machine for rotating a workpiece so as to enable a cutting tool to shape the workpiece into a component of circular cross section.
  • Lathes which are among the most important machine tools, vary widely in design. What they have in common is that the workpiece is given a rotational motion, and the material is cut away by a tool that is given an appropriate combination of linear, axial and radial movements.
  • the main or longitudinal axis of the machine is designated as the z-axis, and the horizontal transverse thereto is designated as the x-axis. This designation of the axes applies to all drawing figures.
  • a toolhead or tool clamping head 2 is journaled in such a way that it can rotate about the axis 3.
  • the toolhead 2 comprises a tool retainer or tool post 4 in which can be mounted and secured tools which are to be fixedly secured, as well as tools which are to be rotated.
  • FIG. 1 shows a tool carrier 5 with a rotating tool 6.
  • the tool 6 is journaled, for example, by antifriction bearings, such as roller bearings 7.
  • a transmission system is arranged in the interior space of the toolhead 2 which system imparts the torque of a drive motor, not shown, in the tool slide 1, for example, via two bevel gear wheels 8 and 9, as well as spur gear 10, to a pinion, bevel gear or similar driver 11 in the tool carrier 5.
  • the pinion 11 is operatively connected to the cutting tool 6. As soon as the tool carrier 5 is removed, during an exchange or replacement of the tool, the pinion 11 is disengaged from the spur gear 10. Conversely, the pinion 11 meshes with the spur gear 10 as soon as the tool carrier 5 is inserted and clamped.
  • Each tool holder or clamp arranged in a tool magazine (chain magazine), not shown, and being driven, for example, with the tool slide which receives a rotating tool, is furnished with such a pinion 11 for operatively engaging or coupling the tool drive. While in the drawing figures a spur gear 10 and a pinion 11 is shown between a drive and a tool, for transmission of force, which transmission can also be disengaged, different arrangements may be provided which allow a desired transmission of torque or motive power and the associated disengagement of such power or force input.
  • FIG. 4 shows the tool 12 after a rotation or movement of the toolhead 2 through 180°.
  • the spur gear 10 is shown in set-back position with respect to the tool retainer 4 in the drawing figures, and the pinion 11 is shown in a manner projecting over the tool carrier 5.
  • a corresponding recess must be provided in the tool retainer 4 such that the tool carrier can be slid in.
  • the axis 3 passes through the line of intersection of the planes 14 and 15 of the tool holder or carrier. These surfaces merely exchange position on rotation or movement of the toolhead, so that the distances to neighboring machine components, especially with respect to a tool magazine for tool exchange, remain constant.
  • the outer contour of the toolhead remains the same also upon rotation or movement. Thus, transfer slides are not required for exchange of tools between a magazine and a clamping head.
  • FIG. 5 shows a toolhead 16 which comprises in the interior space a tool retainer or tool post 22 with a fixed journal 17 for rotating tools 18.
  • the tools 18 are not, in contrast to those shown in FIGS. 1 and 2, respectively arranged so as to be free to rotate in a tool holder, but are directly arranged in the clamping head or toolhead 16.
  • FIG. 5 shows a tool centering cone 19 aside from the journal arrangement 17, as well as showing a spur gear 20, which is the equivalent of spur gear 10.
  • the spur gear 20 meshes with the pinion 21 of the tool retainer or tool post 22.
  • the tool retainer 22 of the toolhead 16 furthermore includes clamp elements 23 with which a tool holder 24, having a cutter or lathe tool 25, can be clamped, as an alternative to the rotating tool 18.
  • the position of the tool holder 24 is defined by the positioning elements 26.
  • the clamping is carried out by the clamp elements 23.
  • clamping can be done in other ways as dictated by the circumstances at hand.
  • the clamp elements 23 can be attached by bolts to the head and similar clamps, straddling the holder 13 or 15 can hold the selected tool holder on the head.
  • FIGS. 5 and 6 The positions of the tools 18 and 25 are shown in FIGS. 5 and 6 in dash-dot outline and by the reference numerals 18' and 25', after the rotation or movement of the toolhead 16 about the axis 27 through an angle of 180°.
  • the relevant contours for the mounting or fastening of tool exchange or replacement devices of the toolhead are also not exceeded by a rotation of 180°, so that also in this embodiment a tool exchange can be carried out in a simple manner.
  • the basic advantage of this embodiment resides in the utilization of the frontal retainer or the like fastener seat for fixed as well as rotating tools.
  • a single retainer is sufficient on a toolhead, whereby the danger of a collision, as it arises in toolheads with several tools, is substantially reduced.
  • the tool carrier 5 and the tool holder or clamp 13 may generically be referred to as a tool holder or tool retainer .
